Hi, I have built an app and it is working fine on the browser. But on the mobile I am getting this error.

net::ERR_NAME_NOT_RESOLVED


The reply from the server is below.

**"HTTP/1.1 200 OK\r\nContent-Type: text/plain\r\nContent-Length: 10\r\nAccess-Control-Allow-Origin: \r\nAccess-Control-Allow-Headers: \r\n\r\n" + ipStr + "";

As you can see, i have the Access Control Allow Origin there also.
Please help as I cant seem to solve the problem.

What I have tried:

I have restarted my phone.
I have cleared the app memory.

What you have shown above is not a valid HTTP reply, it looks more like a line of code. Also, where does the error message come from?

Hi, thanks for reply. Yes you are right, this is the reply code in my server. The error comes on the Android phone which I can see on the console. Basic idea is to use a .local domain to ping the device which in turn gives the IP of the device in the reply. I am getting the reply of IP fine when I use POSTMAN or if I run the app on browser using ionic serve. But on the actual phone this error comes.
